Modelling physical systems with ODEs

"Change is the only constant" - Heraclitus

Ordinary Differential Equations (ODEs) can be used to model any process involving rates of change. Given Heraclitus' insight, you can see why ODEs are such an important tool in mathematical modeling.

The SIR model

Using numerical methods to solve ordinary differential equations.

Period of a pendulum

March 9, 2020
Using Verlet's method to solve the equation of motion of a pendulum, we will compare the true period to the approximated value given by the small-angle approximation.

Magnetic pendulum trajectory

March 12, 2020
A pendulum, made of a magnet, is moving over a surface with three fixed magnets. In this lab, we will determine the trajectory of the magnetic pendulum and explore some of its chaotic behaviour.

Magnetic pendulum map

March 30, 2020
Now that we have a working magnetic pendulum model, let's create a map that shows where the pendulum terminates based on its starting position.
